Central and South America – Overview
Only few uranium deposits of significant size have been discovered in Latin America, to date. This does not imply, however, that the subcontinent is scarce of uranium.
Mexico is the only country with reported uranium deposits in Central America. Deposits are small and largely of volcanic or sandstone type. Well-documented uranium deposits associated with Tertiary volcanic rocks are located in the Sierra de Peña Blanca, Chihuahua state.
